Updated on 2021.09.30 DI-engine-v0.2.0 (beta)


## Introduction to DI-engine (beta)
DI-engine is a generalized Decision Intelligence engine. It supports most basic deep reinforcement learning (DRL) algorithms, such as DQN, PPO, SAC, and domain-specific algorithms like QMIX in multi-agent RL, GAIL in inverse RL, and RND in exploration problems. Various training pipelines and customized decision AI applications are also supported. Have fun with exploration and exploitation.

## Installation

You can simply install DI-engine from PyPI with the following command:
```bash
pip install DI-engine
```

If you use Anaconda or Miniconda, you can install DI-engine from conda-forge through the following command:
```bash
conda install -c opendilab di-engine
```

For more information about installation, you can refer to [installation](https://opendilab.github.io/DI-engine/installation/index.html).

And our dockerhub repo can be found [here](https://hub.docker.com/repository/docker/opendilab/ding)，we prepare `base image` and `env image` with common RL environments.
